“Ultimate battery”: one charge for smartphone, one week for usage
Recently, a research has shown that developing lithium-oxygen battery could bring the idea of an “ultimate battery” to life. Is it possible in the future?
Li-air battery can be the “ultimate battery” we desire…
Lithium-oxygen (aka Li-air) has energy density benefits that are better than current lithium-ion cells and considered as the base for the “ultimate battery“. Specially, it is able to offer ten times the theoretical energy density of current batts, which means we can see smaller, cheaper and longer lasting ones for some small tools or vehicles powered by batts. If we used to think that a “ultimate battery” was just a dream, now the huge potential benefits of Li-air can change your mind thanks to the researchers of the University of Cambridge.
Yes, they have found a way to demonstrate a new kind of cell known as lithium-oxygen which is 90 percent more efficient and stable than what they tried in some experiments before. In addition, it can be recharged more than 2000 times. How amazing! Yet, we also need to be aware of some difficulties in emerging such battery techs. Obviously, it has to keep pace with the machine’s processor and deal with some energy sapping components inside the gadget in order to prevent a decrease in use time.
Besides, they also found an alternative – post-lithium batteries which are essential to automotive development and green energy storage industries but whether it can help create an “ultimate battery” is another story.
“While there are still plenty of fundamental studies that remain to be done, to iron out some of the mechanistic details, the current results are extremely exciting – we are still very much at the development stage, but we’ve shown that there are solutions to some of the tough problems associated with this technology,” – Professor Clare Grey of Cambridge’s Department of Chemistry
Anyhow, it means “ultimate battery” can come true…
Anyhow, we assume that this is a good sign for the idea “ultimate battery”. There are obstacles but at least the researchers are really trying to solve them. If it comes true, smartphones in particular will possibly last all week with just a single charge. Doesn’t it sound great?
